Trawler Fish Suction Mechanism for Continuous Conveyance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Trawling methods are time and labor-consuming due to the need for repeated manual handling of fishing nets to collect and release fish, resulting in low fishing efficiency.
Innovation Solution
A trawler equipped with a fishing and conveying device featuring rotary rods, winches, a fish suction mechanism, and an open-close mechanism that allows continuous fishing and direct conveyance of fish onto the vessel, eliminating the need for manual net handling and improving efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual handling of fishing nets is used to collect and release fish, then the fishing operation can be performed with simple equipment, but the process is time and labor consuming with low fishing efficiency
Solution Approach 1:
The patent replaces the manual mechanical handling system with an automated fish suction mechanism that uses a suction pump and pipeline to automatically convey fish from the fishing net to the storage tank, eliminating the need for repeated manual net handling and significantly improving fishing efficiency while reducing time consumption
Solution Approach 2:
The fishing system performs self-service through the automated suction mechanism that continuously and automatically conveys fish without human intervention, allowing the system to service itself during the fishing operation and thereby reducing labor requirements and time loss
2Productivity
If the fish suction mechanism operates continuously, then fish can be conveyed efficiently onto the trawler, but energy waste occurs when not needed
Solution Approach 1:
The patent implements a feedback control mechanism where the suction pump is activated only when the fishing net contains fish that need to be conveyed, and deactivated when the net is empty or during non-fishing periods, thereby optimizing energy usage based on real-time operational needs and preventing energy waste from unnecessary continuous operation
Solution Approach 2:
The fish suction mechanism operates periodically rather than continuously, activating only during periods when fish need to be conveyed from the net to storage, and remaining inactive during other periods, thus maintaining productivity while avoiding energy waste from unnecessary continuous operation
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution enhances fishing efficiency by continuously conveying fish onto the trawler, reducing labor and time consumption, while preventing energy waste by controlling the fish suction mechanism during operation.
Implementation Method 1
the water flow impacts the spiral deflector on the tapered pipe to drive the tapered pipe to rotate so as to form rotational flow at the left side of the tapered pipe, thus sucking the fish in the fishing net into the net bag
Implementation Method 2
the water flow impacts the elastic rubber membrane to enable the elastic rubber membrane to be concaved inwardly, so that the liquid in the receiving groove is discharged into the lower cavity of the piston cylinder through the conveying pipe to push the piston and the piston cylinder to move upward
